The expressions typeid( SS.b.offsetof ) and typeid( ss3.b.offsetof ) fail with
the error "no property 'offsetof' for type 'char'".

Using typeof in between makes them work, as in typeid( typeof( SS.b.offsetof )
). Changing "offsetof" to "sizeof" also works.

Here's the sample program:

import std.stdio;

struct SS
{
    char a;
    char b;
}

void main()
{
    SS ss3;
    ss3.a = 'A';
    ss3.b = 'L';

    writeln( SS.b.offsetof );
    //writeln( typeid( SS.b.offsetof ) );      // error

    writeln( ss3.b.offsetof );
    //writeln( typeid( ss3.b.offsetof ) );     // error

    writeln( typeid( typeof( SS.b.offsetof ) ) );
    writeln( typeid( typeof( ss3.b.offsetof ) ) );
}

This problem looks related to bugs #3643 and 1684.
But this one is about not getting the type of the "offsetof" standard property.
